and State V of Michigan, has invented? certain new and useful Improvementsiin Latches,

of which the following is a specification.

derstood after the yis the noise in ,slamming the door.

j Thisfinvention relates to latch strikers and latches. It has for its object a combined latch and striker, which will effectively engage and which will wholly eliminate the necessity of a door jamb.V IVhen the 4door j amb i-s used the latch striker incombination withthe latch is so arranged as to arrest the door before same strikes the door j amb. The main object 'of this is to wholly eliminate noise in closing the door and to cooperate for the attainment of this end, the latch is especially constructed so as to be noiseless.

These and other features will be best un! given.

In the drawings:

Fig. 1 is a view of the latch and striker, showing some of the parts broken away, and showing the associated door and door post in section.

Fig. 2 is a cross-section taken on line 2- 2 .of rig. 1.

Fig. 3 is a perspective of the striker.

In a prior application, No. 511,7 61, I have described and claimed a latch, provided with a rubber roll for the latch head. This construction Works very nicely with Va door jamb, but I have found that with the ordinary striker very often the roll type of latch will'carry over the striker socket, conse-` quently will not latch unless the door jamb is used to arrest the movement of the door at the proper time. There are atleast twok "where quiet is desired.

Inconstructing the striker-as shown in my previous application referred to, I prefer to make therstriker surface somewhat description has been sharply'bevelle'd.l The twov bevelsare con nectedjY by a' rounded' hump, c,: iwhich iper'- niits the roller to `roll. vover-xthenhump with-` out injury. v.This :roller is "designatedd: .y fI'n I bevelledwas/atlttl of the latch socket atl?) `is'also somewhat?v i place of naking the rear wall of thelatch l socketof the same projection as kthe front wall, I make it project beyond the front wall forming a projecting abutment, e. `The Vrear'wall is also abrupt in place of being concave as shown Vin my prior application.'

Now by making the rear wall to project beyond the front wall or hump, an abutment is formed which prevents the roll from jumping the latch socket, it'being arrested u' thereby. Especially is this true where the abutment. is so arrangedwith respect to the design of the latch socket, when the latch' roll rests in the latch socket as shown in Fig. 2, thatthe abutment projects slightly beyond the centerline of the roll. When this condition is true, then 4the roll having once enteredthe socket it cannot be forced out of it by pressure against the abutment. The difliculties I have alluded to with respect to the roll type of latch cannot occur with the ordinary bevel type of latch which will drop into its socket and stay.

l/Vhat I claim is:

1. In a door latch, the combination of aV latch provided with a latch head in the form of a roll `and yieldingly projecting, and a latch striker therefor provided with a latch socket, having the rear wall of the socket projecting beyond the front wall of the socket to form an abutmentto arrest the roll in the roll socket.

2. In a door latch, the combination of a easing, a latch projected therefrom by af 'spring and'having a latch head arranged to be disengaged from the latch socket simply by forclng the.. door, and a striker provided with a latch socket having the rear wall thereof projecting beyond the V`front wall tov prevent the Ylatch being disengaged from the latch Vsocket by movement to theV rear thereof.

3. In a door latch', the combination of a latch yieldingly projectingand provided with a( roll type of latch head, and a striker having a latch socket', Vwith the rearfwall projectingrbeyond the front wall forming an abutment extending beyond the centerline of the rollY when the roll rests in the latch Socket. I

4. In a .door latch, the combination of a housing, alatch provided With a roll head,

` slidable in the housing, a spring for yieldingly projecting the saine, and a striker provided with a striker soclet,"havingV an abrupt rear Wall extending beyond the 4Front wall Yforming an abutment to arrest the roll Y head, said striker having-the Yfront Wall of the socket and the striking portion formed on bevels lconnected by a rounded hump, f 4 Y y Y 5; Inv a door latch, the combination of a casing, a latch vslidable therein, and provided with a roll-like head, a spring for yielding-ly projecting the latch, and astrikcasing, a latch slidable therein and provided will a roll head, a spring for projecting the same, andi/a striker having the striker sockA et arranged with the rear Wall abrupt and projecting; Ybeyond the front Wall so that When the latch is in the latch socket the rear Wall projects beyond the center line oi3 the latch roll.

In testimony whereof I affix Inv signature.
